Abstract

A device for collecting and discharging solid particles carried by flowing water, and incorporating a grid structure (15) of stationary and displaceable bars (17, 18), the edges of said bars facing the water flow direction being step-formed, whereby the displaceable bars (18) are interconnected to form at least one unit, which is actuable by means of a driving mechanism (12), which gives the displaceable rods (18) a closed motion path mainly in the place of the rods, the upwards motion component of which is somewhat bigger than the step height of the stationary rods (17). The object of the present invention is to provide a device of the type mentioned in the introduction, which has no displaceable parts below the water level, beside the displaceable rods, which laterally does not leave any open spaces where the water can flow by, and a structural design of the grid whereby this is self-rinsing. The construction furthermore shall be simple, easy to assemble and dismount and almost completely maintenance free. These objects have been solved that the unit of displaceable rods (18) is limited by side plates (36), which are arranged substantially in parallel to the rods and being fixed to the rods, said side plates forming side protections and limiting the grid laterally, that the driving mechanism (12) is arranged to transfer the motion to the displaceable rods (18) via said side plates and that the stationary and/or the displaceable rods (17, 18) on the side turned away from the step-formed side are provided at least partially with saw teeth (38, 42).

BESKRIVNING AV UTFÖRINGSEXEMPEL Uppsamlings och uppfodringsanordningen enligt uppfinningen är såsom är visad i fig} 1 och 2 med sitt stativ 11 placerad i en kulvert 10 eller ränna. genom vilken vattnet strömmar som 'šfly b» IL" 448' 106 skall renas. På stativet är bl.a anordnad en drivmotor 12 med tillhörande växel K13. för.drivning av två par exenterskivor '21, vilka uppbär anordningens uppfodringsdel 15 och bibringar denna dess uppfodringsrörelse.DESCRIPTION OF EMBODIMENTS The collecting and feeding device according to the invention is as shown in Figs. 1 and 2 with its stand 11 placed in a culvert 10 or gutter. through which the water flows as 'šfly b »IL" 448' 106 is to be purified. On the stand is arranged, among other things, a drive motor 12 with associated gear K13. for driving two pairs of eccentric discs '21, which support the feeding part 15 of the device and impart this its feeding movement.

UppFodringsdelen_ 15 består av ett stort antal parallella stavar med trappstegsformade sidokanter. vilka är vända mot det i pilens 16 riktning inkommande vattnet, t.ex avloppsvatten. varannan stav 17 är fast och varannan stav. 18 är rörligt anordnad. Uppsåttningen stavar bildar sålunda en fast gallerdel och en rörlig -gallerdel, varvid de rörliga stavarna 18 Följer excenterskivornas rörelse. vilket i det visade - utföringsexemplet betyder att de rörliga trappavsatserna 19 utför en sluten cirkulär rörelsebana 22.The feeding part_15 consists of a large number of parallel rods with step-shaped side edges. which are facing the water entering in the direction of the arrow 16, eg waste water. every other rod 17 is fixed and every other rod. 18 is movably arranged. The mounting rods thus form a fixed grid part and a movable grid part, the movable rods 18 following the movement of the eccentric discs. which in the embodiment shown means that the movable landing 19 performs a closed circular path of movement 22.

Avsatserna 19 hos respektive stavarna är belägna väsentligen horisontellt eller luta svagt bakåt sett från avsatsernas framkant då anordningen är monterad i operativ position i kulverten 10.The ledges 19 of the respective rods are located substantially horizontally or tilt slightly backwards seen from the leading edge of the ledges when the device is mounted in the operative position in the culvert 10.

Uppfodringsdelen 15 sträcker sig ett stycke ovanför kulverten 10 och bildar i.princip en enhet utgörande kombinerat galler och trappstegstransportör, Gallrets fasta stavar 1?_är i sin övre och nedre del förbundna med varandra medelst på underkanten fästade förbindelseorgan 31 och 32. t.ex i form av fastsvetsade plattjärn, bildande, _ ett paket, som i sin övre del är Fäst till vid stativet anordnade Fästen V33, medan den nedre delen stöder mot och år fäst till kulvertens 10 botten. Även de rörliga stavarna 18 bildar ett sammanhängande paket och är för detta ändamål utbildade med ett nedåt utskjutande parti 34, på vars undersida 'är fastsvetsade tvärgående förbindelseorgan 35. likaledes i form av plattjärn eller liknande. De båda yttersta stavarna i det rörliga paketet är utformade som sidoplåtar 36. med. avsevärt större höjd ån övriga stavar och saknar trappstegen 19. Även dessa sidoplåtar 35 är Fastsvetsade vid Förbindelseorganen 35. Paketet med de rörliga stavarna 18~ är upphängt i sidoplåtarna 36. via relativt dessa svângbara armar 44s 10e 4 26 samt en vid vardera* sidoplåten anordnad fast tarm 27,' Armarna 25 och 27 är roterbart lagrade vid exenterskivorna 21a Sidoplåtarna 36 som begränsar gallret i sidled, har till syfte att förhindra att det uppfodrade godset 30 inte faller ner längs gallrets sidor och tillbaka till den silade vätskan. Med hjälp av fråni kulvertens 10 sidoväggar sig sträckande och sidoplåtarna 38 överlappade ledskenor 4A styres vattnet mot uppfodringsenheten 15. Även monteringsmässigt erbjuder @konstruktionen med de fasta sidoplåtarna 38 stora fördelar. eftersom hela paketet kan tillverkas och monteras på fabrik. Skulle ett haveri uppkomma kan genom enkla handgrepp. Såväl det fasta som det rörliga paketet. vardera som en sammanhängande enhet, bytas ut mot nya sådana på mycket kort tid._ Föroreningarna 'som åtföljer avloppsflödet genom kulverten 10 kommer således att stoppas upp av det galler som bildas av stavarna 17 och 18. Beroende på den speciella inbördes rörelsen mellan stavarnas horisontella avsatser _19, erhålles en vertikal "nettorörelsekomponent, som Uppfordrar godset succesivt uppåt längs de fasta stavarna 1? trappavsatser. allt eftersom de .rörliga ravsatserna utför sin håmtnings- och avlämningsrörelse.The lining part 15 extends a distance above the culvert 10 and forms in principle a unit constituting a combined grid and step conveyor. The fixed rods 1 of the grid 1 are connected to each other in their upper and lower part by means of connecting means 31 and 32 attached to the lower edge. in the form of welded flat iron, forming a package, which in its upper part is attached to the brackets V33 arranged at the frame, while the lower part supports and is attached to the bottom of the culvert 10. The movable rods 18 also form a continuous package and are for this purpose formed with a downwardly projecting portion 34, on the underside of which transverse connecting means 35 are welded, likewise in the form of flat iron or the like. The two outermost rods in the movable package are designed as side plates 36. with. considerably greater height than the other rods and lacks the steps 19. These side plates 35 are also welded to the connecting members 35. The package with the movable rods 18 ~ is suspended in the side plates 36. via relatively these pivotable arms 44s 10e 4 26 and a side plate arranged at each * solid casing 27, The arms 25 and 27 are rotatably mounted on the eccentric discs 21a. The side plates 36, which limit the grate laterally, have the purpose of preventing the lined goods 30 from falling down the sides of the grate and back to the filtered liquid. By means of extending from the side walls of the culvert 10 and the guide plates 4A overlapping the side plates 38, the water is directed towards the feeding unit 15. Also in terms of assembly, the construction with the fixed side plates 38 offers great advantages. because the whole package can be manufactured and assembled at the factory. Should an accident occur, it can be done through simple operations. Both the fixed and the movable package. each as a coherent unit, are replaced by new ones in a very short time.The contaminants' accompanying the effluent flow through the culvert 10 will thus be stopped by the grid formed by the rods 17 and 18. Depending on the particular mutual movement between the horizontal ledges _19, a vertical "net movement component is obtained, which encourages the goods successively upwards along the fixed bars 1" stair ledges. as the .moving amber ledges perform their retrieval and delivery movement.

Avloppsvatten eller liknande innehåller ofta stora mängder hår och fiber, men även plastpåsar och dylikt, som kanr fastna bakom stavarnas bärkonstruktion, dvs. förbindelseorganen 31 och 35. så att inom relativt kort tid gallret blockeras mer eller mindre eller t,o.m försvårar eller förhindra en relativ rörelse stavarna emellan. Det har vidare tidigare varit ett' problem att, transportera det uppfodrade materialet 30 bort från det översta trappsteget. så att detta kan tas hand om' av en efterföljande transportör, exempelvis ett ändlöst band 37.Wastewater or the like often contains large amounts of hair and fiber, but also plastic bags and the like, which can get stuck behind the supporting structure of the rods, ie. connecting means 31 and 35. so that in a relatively short time the grid is blocked more or less or even obstructs or prevents a relative movement between the rods. Furthermore, it has previously been a problem to transport the lined material 30 away from the top step. so that this can be taken care of by a subsequent conveyor, for example an endless belt 37.

För att undvika igensåttningen av gallret förses lämpligen de fasta -stavarna- 17 på sin från trappstegen 19 vända dnderkant med sågtänder 38 eller liknande. åtminstone vid de partier somfl är belägna mitt för de rörliga stavarnas 18 förbindelseorgan 35. Varje gång de rörliga stavarna utför ett arbetsslag, dvs u* “ 448 106 en sluten cirkulär rörelsebana 22, kommer sågtänderna 36 vid plattjärnens 35 passage förbi dessa att riva loss eventuella föremål som har 'fastnat på plattjärnen. En ytterligare rensingseffekt mellan stavarna 17 och 18 erhålles med hjälp'av vid dessa fast anordnade distans- och rensningsorgan 39, vilka lämpligen är anordnade parallellt med vattnets strömnings- riktning och fastsvetsade på de ¥asta och/eller de rörliga, stavarnas ena eller. båda flatsidor. Rensningsorganen 39 är anbragta i höjd med respektive avsats 19. men det är även tänkbart att anordna dessa glesare vid exempelvis vartannat eller vart tredje trappsteg.To avoid clogging of the grid, the fixed rods 17 on their lower edge facing the steps 19 are suitably provided with saw teeth 38 or the like. at least at the portions which are located in the middle of the connecting means 35 of the movable rods 18. Each time the movable rods perform a working stroke, i.e. in a closed circular path of movement 22, the saw teeth 36 at the passage of the flat iron 35 past them will tear off any objects that have 'stuck' to the flat iron. An additional cleaning effect between the rods 17 and 18 is obtained by means of these fixedly spaced and cleaning means 39, which are suitably arranged parallel to the direction of flow of the water and welded to one of the and / or the movable rods. both flat sides. The cleaning means 39 are arranged at the height of the respective ledge 19. but it is also conceivable to arrange these sparser at, for example, every second or every third step.

Den fortsatta frammatningen av uppfodringsgodset. sedan detta har nått översta trappsteget, erhålles med hjälp av vid såväl de fasta som de rörliga stavarnas övre ände utformade förlängda partier #0 ooh 41. vilka är anordnade horisontella eller 'svagt lutande i riktning från det översta trappstegetj För att förhindra att föremål kan fastna mellan stavarna är de rörliga 'stavarnas 18 förlängda partier 41 inom detta område utformade med sådan tjocklek att utrymmet mellan de fasta stavarna 17 är väsentligen utfyllt, så att endast ett ringa spel återstär, såsom även är visad i fig. 5. För att även inom detta område förhindra hår och andra Föremål att fastna i de Fasta stavarnas _17 Förbindelseorgan 31 är lämpligen underkanterna_ av de rörliga stavarnas 18 partier 41 försedda med sågtånder 42. som på samma sätt som sâgtänderna 38 vid» varje arbetsslag kommer så nära förbindelseorganet 31 att en rensning sker.The continued feeding of the feedstock. since it has reached the top step, is obtained by means of elongated portions # 0 ooh 41. formed at both the upper end of the fixed and the movable rods which are arranged horizontally or slightly inclined in the direction from the top step. To prevent objects from getting stuck between the rods, the elongated portions 41 of the movable rods 18 in this area are formed with such a thickness that the space between the fixed rods 17 is substantially filled, so that only a small clearance remains, as also shown in Fig. 5. this area prevents hair and other objects from getting stuck in the fixed rods 17 Connecting means 31 are suitably the lower edges of the portions 41 of the movable rods 18 provided with saw teeth 42. which in the same way as the saw teeth 38 at each work stroke come so close to the connecting means 31 that a cleaning happens.

För. att förhindra att gallrets nedersta del vid de rörliga 'stavarnas uppåtgående slag, öppnas motsvarande dubbla spaltbredden och därigenom möjliggöra större föremål att passera genom dessa spalter, är de_fasta stavarna 17, såsom framgår av figur 4. i sin nedre del utformade med större godstjocklek, så att när de rörliga stavarna 18 befinner sig i sitt nedre 'läge spalterna inom gallrets nedersta parti 43 är väsentligen tillslutna. ' Vissa typer av föremål som Följer med i det strömmande vattnet 448 106 kan vara svåra att transportera 'på - anordningen enligt uppfinningen. då dešsa föremål kan rulla eller glida av stegens horisontella avsatsef. Sådana förmâl kan vara flaskor, burkar men även stockar och liknande. För att möjliggöra även en uppfodring av dvlika föremål föreslås, så 'som Framgår av utförningsexemplet i figur 6, aft trappstegens avsatser 19 hos såväl de Fasta som de röfliga stavarna 17, 18 utformas med urskålad eller nedåt avsmalnande form.For. to prevent the lower part of the grid from opening at the upward stroke of the movable rods, corresponding to twice the gap width and thereby enabling larger objects to pass through these gaps, the fixed rods 17, as shown in Figure 4, are formed in their lower part with greater wall thickness, so that when the movable rods 18 are in their lower position the gaps within the lower part 43 of the grid are substantially closed. Certain types of objects that accompany the flowing water 448 106 may be difficult to transport on the device according to the invention. as these objects can roll or slide off the horizontal ledge of the steps. Such purposes can be bottles, cans but also logs and the like. In order also to enable a feeding of such objects, it is proposed, as can be seen from the exemplary embodiment in Figure 6, that the ledges 19 of the steps of both the fixed and the rough rods 17, 18 be designed with a hollowed-out or downwardly tapering shape.
